METHOD OF AND MEANS FOR DISPLAYING A FIXED PICTURE IN CONJUNCTION WITH ASERIES OF SYMBOLS FOR CONVEYING RELATED IDEAS.

Application filed July 1a, 1926; Serial No. 123,522.

tention and convey the thought desired inapicture unaided by readingmatter. My principal object is to combine an appropriate conversationwith a picture in such a manner as to arrest and hold the interest ofthe observer and to consecutively convey the desired thoughts. Generallythe parts 'of a conversation will appear one at a time, and in orderlysequence, and the conversationmay be between two or more persons.

One looking at such a picture will take in at a glance the subject as awhole, will read,

each statement as it appears and his interest having been arousedQwillcontinue toread until the conversation has-been com-' pleted. If all thestatements appeared at once even if space permitted,there would benothing to arouse the curiosity and one lookingat the picture would passon without reading the statements. It must also be borne in mind thatthings that move'attract the'attention.

Another object of my'invention is to bring such a combined picture andconversation within arelatively small space, and make its productionpossible at a reasonable cost;

My invention permits the conveying of a continuing thought as with stripcartoons,

within the space of a single picture, and is therefore valuable for manypurposes, particularly in advertising'and as an educational medium.

In-the particular embodiment of my in Fig. 4, is the plate carrier forthe several Figure 1 is a perspective of an illuminated Similarly bar a"is pivoted toward its midelements of theconversation which appear to becontributed by one. of the persons in the advertising picture, and

Fig 5, is the plate carrier for the elements of the conversation of theother person.

Referring now to the drawings and particularly to Figs. 1 and 2, C isthe cabinet in which the whole mechanism is housed. The front of thecabinet 0 is made of glass, and on its back surface ismounted thepicture 0 shown in Fig. 3, the circles 0 0 where the elements of theconversations are to appear "being preferably a solid color in keepingwiththe picture as a whole. Thepicture c is illuminated by means of theelectric lights 0. -Back of the lights a is a vertical artitionc, withopenings 0, 0 through wiich the image of the wording on the plates B, Bhereinafter described is projected.

Within the main chamber of the casing C back of the partition 0 arelocated the plate carriers, B, B the latter carrying the plates, 6 b, band b with elements of the contributions of Jane to the conversation andthe former carrying the plates 6, b, b and b with elements of thecontributions of Ruth .to the conversation.

' The mechanism for rotating the plate carriers consists of a sprocketwheel A, fixed to the shaft a, journalled in the bearing a mounted onthe support a. The shaft a has a worm wheel a driven by the motor M.

The sprocket wheel A has a chain a which drives the s rocket wheel a,fixed to the shaft a whlch is journalled in the cross piece a".

Fixed to the shaft a is a rotating fin er a adapted to contact with luga, on the ar q ,'which is parallel with bar a", thus moving the bar a"to the right as shown in dotted lines, in Fig. 2. An upstanding bar a ispivoted toward its middle on shaft a" along with bar a", at its bottomis secured by pivot a" to bar a and at its top carries a pawl a" whichis ada ted to coact with the teeth of ratchet whee a! fixed to shaft(1", to rotate said shaft, to the inner end of which the plate carrier Bis fixed.

Immediately back of the plate carriers B and B are electric lights, D, Drespective ly, each in a light tight casing d, (1 respectively, D beingdirectly back of the circle 0 and D directly backof 0 Each of the plates6 b b 'and b" is adapted upon rotation of the plate B to be broughtdirectly between the lamp D and the display space 0 and a magic lanternlens (2 in the tube d is adapted to project a suitable enlargement ofthe matter on the aligned plate upon-the display space 0 Similarly eachof the plates 6 ,1), 6 and b is adapted upon rotation of the plate B tobe brought directv1y between the lamp D and the display space 0 and amagic lantern lens in the tube (Z is adapted to project a suitableenlargement of the matter on the aligned plate upon the display space 0The lights D and D are lighted alternately and after the plate carriershave come to rest with a plate aligned. The

switch for turning, them on and off isprovided on a revolving disc E ofinsulating material fixed to the shaft a. Disc E has.

arcs e, e of brass or other conducting material on opposite edges of theperiphery, and

at opposite sides of thediscs. The shaft a also carries another disc- Falso of insulating material, and having a collar f of brass or otherconducting material.

sufficiently to bring the brush 6 into contact fwith its are 6 as shownin Fig. 1, the lamp D will be lighted and the plate 1) being in shaft aand its attached elements carries the are e out of contact with thebrush a, and thelight D goes out. Space 0 then becomes dark, leavingboth spaces 0 and a dark for the moment. I

A little further rotation oft-he shaft (1, brings the are e into contactwith the brush a, and lights the lamp D, and the plate 6 being inregistering position in front-0f the lamp D, there will appear on thepic'- ture in the space 0 the words, A long cherished wish my dear.
